COMBINATION SOLE-PLATE AND BAILRQAD-TIE.

Specification of Letters Patent.

I To all whom it may concern:

Be it known that I, Gor'rrnrnn H. J. Whats, a subject of the King of Prussia, German Emperor, and a resident of 88 Schlossstrasse, in the city of Berlin-Steglitz, Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Combination Sole-Plates and Railroad-Ties, of which the following is a specification. r

The invention herein illustrated relates to an improvement of the fastening of the rails to the metallic cross-ties in order to preserve the ties longer and make them more durable. This improvement, applicable to all metallic cross-ties and shown with the tie, illustrated in the American Letters Patents of November 24th 1903 No. 744868 and of July 30th 1912 No. 1034389, is explained in the accompanying drawings, in which Figure 1 is a cross-section through an intermediate tie with view of the sole-plate and rail,1n approximate measure 1 :10; Fi 2 is a cross-section through a joint-tic wit 1 a view of the sole-plate and rail; Figs. 3 and 4 are plans of Figs. 1 and 2; Fig. 5 is a longitudinal section through the tie and the sole-plate; Fig. 6 is a cross-section through an intermediate tie and the soleplate on larger scale, approximately 113; Fig. 7 is a plan of a sole-plate for an intermediate tie; Fig. 8 is a cross-section of the sole-plate of Fig. 7 Fig. 9 is a cross-section through a joint tie and the sole-plate thereof; Fig. 10 is a longitudinal section through the intermediate or joint tie and the soleplate thereof on the line H of Figs. 7 and 11; Fig. 11 is a plan of the sole-plate for the joint tie; Fig. 12 is a longitudinal section through the sole-plate of thejoint tie on the line mm of Fig. 11; Figs. 13, 14, 15 and 16 show lcss important small iron fittings for fastening the rail at the soleplate.

For greater clearness sake the fish-plates at the rail-joints are omitted in the draw- Experience with metallic cross-ties has proved, that these ties become prematurely useless only because fissures or slits break out near the holes of the tie, which are, made for small iron fittin s, to fasten the soleplate and the rail, t ese holes weaken the carrying capacity of the tie especially at the point, Where the rail lying and here j the tie must have the greatest power of resistance. In order to remove this fault and to avoid the perforation of the tie at this spot, the tie is provided at the top with thicker side-ribs 1, which have slots 8 cut out at the inner sides, in which the sole-plates enter by projecting keys 7c. The sole-plates are shoved in from the head end of the tie and secured against lifting-oil by the slot and keyl' In order to avoid also a dislocating .or movingbf the sole-plates in the longitudinal direction of the tie, the sole-plates are arrested by gage-bars Z),.which are fixed by V one bolt in the center of the tie. For the widening of the gage at curves, the outside gage-bar is prolonged as wanted. For {as toning; the rail to the sole-plate, a hook is provided at the outside of the sole-plate and at the inner side of the sole-plate a corresponding cli with headed-bolt is seen, the head or dou 1e hook of which lies in a slot 3, which is grooved in the under-side of the sole-plate, about 30 mm. thick, and which has only such breadth, that the hook of the headed bo-ltrhas a firm and strong seating place therein without being able to turn around. This headed bolt is to be stuck into the hole of the sole-plate, before shoving in the sole-plate in the slots 8 of the tie. The same is true of the headed bolt of the gage bar. Consequently the tie has only one little hole in the center of its length for fastening the gage-bar at that point, where fissures.

cause no damage to the tie. By locationof the holes of the ties according to the line of the track, the track itself maybe adjust ed simultaneoiisly.

The ties as shown in the drawings may be rolled and finished and after that only need the cutting of the slots for the keys of the sol plate from the head end of the tie to theiseat of the sole-plate. The sole-plates arefrolled crosswise, i. e. in the direction of the .rail, and the slot S out out in the underside. In the sole-plate for the rail-joint, which bears the both rail ends of the railjoint-compare above named Letters Patents-there are to be out two slots S in the underside, and in the upperside the recess for the taking-up or facing rail end. The sole-plates can also be cast without addi-' tional work. The gage-bars are to be made of flat bar iron...

What I claim as my invention is:

Combination of the sole plate with the railroad tie, the tie having an imperforate In witness whereof I have hereunto signed top under and near the seat; of the sole plate my name in presence of two wltnessee and ribs with slots, the sole plate having Berlin-Steglitz, September 7th 1912.
